Abstract
A wire netting, in particular a safety net, includes a plurality of helices which are braided with one another and at least one of which is manufactured of at least one single wire, a wire bundle, a wire strand, a wire rope and/or another longitudinal element with at least one wire, in particular made of a high-tensile steel. The wire is bendable in a reverse bend test in opposite directions, by at least 90° respectively, about at least one bending cylinder having a diameter of maximally 2 d, at least M times without breaking, wherein M may be determined (by rounding down if applicable) to be C·R−0.5·d−0.5 and wherein a diameter d of the wire is given in mm, R is a tensile strength of the wire in N mm−2 and C is a factor of at least 400 N0.5 mm0.5.
Claims9
A wire netting comprising:
- a plurality of helices which are braided with one another and at least one of which is manufactured of at least one single wire, a wire bundle, a wire strand, a wire rope, and/or another longitudinal element, which are each formed from at least one wire, in particular made of a high-tensile steel, wherein
- the wire is bendable in a reverse bend test in opposite directions, by at least 90° respectively, about at least one bending cylinder having a diameter of maximally 2 d, at least M times without breaking, wherein M may be determined (by rounding down if applicable) to be C·R−0.5·d−0.5 and wherein a diameter d of the wire is given in mm, R is a tensile strength of the wire in N mm−2 and C is a factor of at least 400 N0.5 mm0.5.
A method for an identification of a suitable wire, in particular a wire made of a high-tensile steel, and for manufacture of a wire netting with a plurality of helices which are braided with one another, wherein at least one of the helices is to be manufactured of at least one single wire, a wire bundle, a wire strand, a wire rope and/or another longitudinal element with the suitable wire, comprising:
- performing a reverse bend test in which a test piece of the wire is bended in opposite directions, by at least 90° respectively, about at least one bending cylinder having a diameter of maximally 2 d, at least M times without breaking, wherein M may be determined (by rounding down if applicable) to be C·R−0.5·d−0.5, and wherein a diameter d of the wire is given in mm, R is a tensile strength of the wire in N mm−2 and C is a factor of at least 400 N0.5 mm0.5;
- and
- identifying the wire as suitable in response to the test piece of wire not breaking in the reverse bend test.
